Answer:
1+√21 /2 and 1-√21 /2
Step by step explaination:
1/x+5=1/x²
x+5=x²
x²-x-5=0
comparing with ax²+bx+c=0 weget,
a=1, b= -1, c= -5
b²-4ac= (-1)²- 4×1×(-5)= 1-(-20)=1+20=21..
By using formula
x= -b+-√b²-4ac/2a
x=-(-1)+-√21 /2×1
x= 1+-√21 /2
x= 1+√21 / 2. OR. x= 1-√21 /2
1+√21 / 2 and 1-√21 /2 are roots of given quadratic equation..
